Product details
Overview
DF36057FZJV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36057 Group, featuring the H8/300H CPU core, 512 KB on-chip ROM, 32 KB RAM, and integrated peripherals including SCI, I2C, and 16-bit timers. It operates at up to 20 MHz, supports 5 V operation, and targets embedded control applications requiring deterministic real-time response and on-chip nonvolatile program storage.
For engineers reviewing the DF36057FZJV datasheet, DF36057FZJV pinout, DF36057FZJV application, or DF36057FZJV equivalent, key selection criteria include its 100-pin LQFP package, ROM-based execution architecture, H8/300H instruction set compatibility, and support for on-board programming via SCI3 channel 1 (P21/RXD, P22/TXD) in boot mode.
Technical Context
The DF36057FZJV implements the H8/300H CPU core with 24-bit address space, supporting both big-endian and little-endian data access modes. Its memory map includes dedicated areas for on-chip ROM (0x000000–0x07FFFF), RAM (0xFFE000–0xFFFFFF), and peripheral registers (0xF00000–0xF00FFF).
It integrates system-level functions including a programmable clock pulse generator with crystal/ceramic resonator support, four power-down modes (Sleep, Standby, Subsleep, Subactive), and module standby control for selective peripheral gating. Reset handling follows a defined vector at 0xFFFFF0, and exception processing supports 64 interrupt vectors with configurable edge-triggered external interrupts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300, enabling legacy code reuse and toolchain continuity. |
| ROM Capacity | 512 KB on-chip Flash ROM (0x000000–0x07FFFF), eliminating need for external program memory in cost-sensitive designs. |
| RAM Size | 32 KB on-chip RAM (0xFFE000–0xFFFFFF), sufficient for real-time stack, buffers, and firmware variables without external SRAM. |
| Max Operating Frequency | 20 MHz system clock, delivering ~12.5 MIPS performance suitable for motor control, industrial I/O, and protocol stacks. |
| Supply Voltage | 4.5 V to 5.5 V operation, compatible with standard 5 V logic systems and legacy industrial power rails. |

| I/O Pins | 81 CMOS bidirectional I/O pins with programmable pull-up resistors, enabling direct interface to sensors, displays, and discrete actuators. |
Pinout & Package
DF36057FZJV is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per the H8/36057 Group Hardware Manual Rev.4.00 (2006), with dedicated reset (RES), clock input (XIN/XOUT), and multiple peripheral I/O groups mapped across port registers P0–P11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES | Active-low reset input | Asynchronous hardware reset; must be held low ≥1024 cycles after power stabilization to guarantee internal register initialization. |
| XIN / XOUT | Crystal oscillator input/output | Supports 1–20 MHz crystal or ceramic resonator; internal oscillator circuit eliminates need for external clock generator. |
| P21 / P22 | SCI3 channel 1 RXD/TXD | Used for on-board programming in boot mode; requires external level-shifting if interfacing with RS-232 transceivers. |
| P85 / P86 / P87 | On-chip emulator (E7/E8) interface | Reserved when using E7/E8 debugger; unavailable for user I/O unless external hardware bypasses emulator signals. |
| VCC / VSS | Power supply / ground | Multiple dedicated VCC/VSS pairs ensure stable core and I/O rail decoupling; thermal pad must be soldered to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash ROM with erase/write control | Enables field firmware updates via SCI3 boot loader without external programmer; FLMCR1/FLMCR2 registers allow block-level erase and byte/word programming. |
| Four power-down modes with wake-up sources | Reduces active current to ≤10 µA in Subsleep mode while retaining RAM content and allowing wake-up via external interrupt or timer match event. |
| Programmable clock generator with prescaler S | Supports flexible clock tree configuration: main oscillator → prescaler S → system clock, enabling precise frequency division for peripheral timing (e.g., SCI baud rate generation). |
| Dedicated SCI, I²C, and 16-bit timer modules | Provides autonomous serial communication and timing without CPU intervention-critical for real-time sensor polling and actuator control loops. |
| Interrupt vector table with 64 entries | Allows prioritized, low-latency response to asynchronous events (e.g., encoder pulses, fault signals) with ≤6-cycle interrupt entry time in active mode. |

FAQ
What is the maximum operating frequency of the DF36057FZJV?
The DF36057FZJV supports a maximum system clock frequency of 20 MHz when using an external crystal or ceramic resonator. This frequency is achieved through the internal clock pulse generator and prescaler S configuration, enabling deterministic instruction execution at approximately 12.5 MIPS. The DF36057FZJV must be operated within its specified 4.5 V to 5.5 V supply range to maintain timing compliance at this speed.
Does the DF36057FZJV support in-system programming?
Yes, the DF36057FZJV supports in-system programming via its SCI3 channel 1 (P21/RXD and P22/TXD) in boot mode. This allows firmware updates without removing the device from the PCB. The DF36057FZJV's on-chip Flash ROM is organized into blocks managed by FLMCR1 and FLMCR2 registers, enabling sector erase and byte/word programming under firmware control.
What power-saving modes does the DF36057FZJV offer?
The DF36057FZJV provides four power-down modes: Sleep, Standby, Subsleep, and Subactive. In Subsleep mode, current consumption drops to ≤10 µA while retaining RAM content and enabling wake-up via external interrupt or timer match. Mode transitions are controlled via SYSCR1, SYSCR2, and MSTCR1 registers, allowing fine-grained peripheral gating and clock stopping.
Is the DF36057FZJV pin-compatible with other H8/36057 Group devices?
Yes, the DF36057FZJV shares the same 100-pin LQFP package and pinout with all members of the H8/36057 Group, including HD64F36057, HD64F36057G, HD64336057, and HD64336057G. Differences between these variants lie in mask ROM vs. Flash ROM, lead-free compliance, and test configurations-not in pin assignment or electrical interface behavior.
What development tools are supported for the DF36057FZJV?
The DF36057FZJV is supported by Renesas' H8S/H8/300 Series C/C++ Compiler (REJ10B0058), High-Performance Embedded Workshop 3 (REJ10B0026), and the E7/E8 on-chip emulators. Debugging requires reserving P85–P87 and the NMI pin; for production programming, the DF36057FZJV's SCI3 boot loader enables host-based firmware loading without emulator hardware.
